BUNDLING DEVCE FOB, LUMBlER-TRMMING MiCNES AND THE LKE.

To all whom it may concern:

Be it known that l, EDWARD B. WimmersoN, a citizen of the United States, and resident of Richmond, Virginia, have invented certain new and useful improvements in. Bundling Devices for Lumber-Trimming Machines and the like, of which the following is a specification.

My present invention relates to improve ments in bundling devices for lumber trimming machines for trimming the ends of pickets, laths, copper sticks and the like,

and aims to produce a simple, economical, durable and efficient machine possessed of various features of novelty and utility as will hereinafter appear.

My said invention is defined by 'the appended claims and an embodiment thereof is illustrated in the accompanying drawings, .in which- Figure l is a side elevation of the machine.

Fig. 2 is a plan view.

Fig. 3 is a rear elevation.

Fig. l is a detail elevation, partly in section, and

Fig. 5 is a'sectional de'taiL Referring by reference characters to these drawings, the numeral l designates a Suitable frame supported by standards la, which frame supports, in suitable bearings, a saw carrying shaft 2 provided with a pair of circular saws 3 and 3a located a distance apart corresponding to the length of the picket, lath, or other article to be trimmed.

85 This shaft may be driven in any suitable manner, conveniently by a belt Ll passing over a pulley 2a on shaft 2 and over a pulley 5a on main drive shaft 5 which may receive its motion from any suitable prime mover.

lfhe articles to be trimmed are successively fed from a supply at the front of the machine by endless chains or conveyers 6 which pass around driving sprockets 7 fast on a shaft S at the rear of the machine frame, and around idle sprockets 9 at the front. Shaft 8 may conveniently be driven by belt l0 from the main drive shaft 5, The endless chains or conveyers are provided with projections or liights 6a designed to successively engage the lowermost pickets or strips of the pile at the front of the machine and to convey them past the saws, and during such conveying action the chains areguidcd in trough or channel shaped memce bers l1, the flights projecting sultlciently Specification of :Letters Patent.

above the edges of the guides to engage the carried by or formed integral with bracket irons 25a secured to the frame work of the machine at the rear end, which bracket irons are inclined so as to cause the trimmed artlcles tobe deflected downwardly into the U-shaped arms. Additional supporting and bracing brackets 26 may be provided, as also the cross bar 26e.

These U-shaped arms carry a pair of chains 27 suitably connected to the rear ends of the arms at 28, the opposite ends of the chains being connected to a rod 29 designed to be supported by recessed lugs 30. These chains are for the purpose of compressing the strips into hrm bundles preparatory to their being tied together by the operator and this is accomplished, after the requisite number of articles have been dropped into the U-shaped arms by the operator drawing the rod 29 across over the top of the assembled strips and engaging the same with the hook 3la of a rod 3l pivotally connected to a foot lever 32. After such engagement of the central portion of the rod 29 with the hook 3l, the foot lever may be depressed to tighten the chains about the assembled strips, the operators hands being left free to pass the cord about the bundle and secure it around the same.

lt is desirable that means be provided for automatically cutting off the supply of articles to 'the bundling device after a prede` termined number has been accumulated therein and without stopping the machine,

and for this purpose l provide a lever 33' suitably pivoted in the frame of the machine and having an end 33a projected upwardly into position to be struck and depressed by the articles as they are fed rearwardly by the conveyer chains. This lever 33 carries a pawl 3d acting to turn a ratchet wheel 35 step by step. Means to limit the upward position of the lever 33 are provided in the shape of a grooved guide block 33b mounted on the frame and carrying a set screw 33C which regulates the position of the lever 33. Ratchet wheel 35 is provided with a plurality of holes adapted to receive one or more pins 36. rl`hese pins are adapted to strike one arm 37a of a piv oted lever, the other arm 37b of which rests beneath the rear arm 3)8l of a rock shaft 3S, Which has an arm 38 provided withV ahook. 38. A lever 39. is pivotally suppoii'ted'from a bracket 40 and carries a counter-Weight 239il at one end, and a forked portion at itsV opposite end in which is :mounted a rod 40%.- To the endsof this rod 40a are connected arms 4l which have slotted portions slidably guided by pins 42 secured to the brackets 25a. After a certain number of strips or articles have accumulated in the U-shaped arms 25 one of the pins .36 will Contact `with arm 37d which will disengage the hook. 38C from the rod carrying the a'rm's 4l and allow these arms to be projected upwardly iiito the position Ain dotted lines in Fig. l by the action of the counteriveight 39a; This will obstruct the passage of the articles do'ivii the inclined brackets 2-5a for a sutlicient period of time to enable the operator to bundle the previously assembled articles and remove them from the receiver and replace the chains, whereupon the operator will reset the parts.

In order that the receiver may be at the proper height to enable the-operator to conveniently bundle the articles Without caus! ing too great an elevation at the front of the machine, I cause the conveyers to travel upwardly in an inclined path toward the rear oit the machine, as shown in Fig. l.

It Will be obvious that the machine may be set to effect the delivery of any predetermined number of articles into the receiving arms. For instance, if the ratchet Wheel 35 beprovided With one hundred teeth and one pin be used one hundred articles Would bedelivered into the receiving arms before the delivery Was interrupted, While if two diametrically opposed pins Were used only fifty Would be delivered prior to such interruption and so on.

To prevent. the latch Wheel 35 from movf ing backivaid'ly on the 'return movement of the pavvl 34, I prefer to'mount it in the manner shown morey in detail in Fig. 5., by reference to which it will be seen that 'the Gop'ie's 'of this patent 'may be obtained for vfive cents each, by ai'ss'ing'th'e `ri"Consa'Tner of Za'teiits,

articles, a receiver atthe rear end ofthe* machine, and inclined members lior'deliv-v eriiig said articles from the conveyers to the receiver, of means for Vinterrupting the` delivery of strips to said receiver comprising a pair of arms guided to movetransversely of said inclined members, a Weighted lever connected to project 'said arms, a re,-V taiiiing device for holding said arms reof a predetermined number of strips forautomaticalfly operating said retaining device.

2. In combination, an endless conveyer for articles, a receiver into which said articles are delivered, fiexible compressing means permanently connected to one side of said receiver and detachably connected with the other side yand means adapted to be connected with theY detachable ends of said flexible elements for tightening' them around the assembled strips.

BfIii combination, an endless conveyer for articles, a receiver into which said articles are delivered comprising Ushapedl bars, chains each having one end connected to one end of a fU-sliapedbar, a rod connected to the other ends oit' said chains, means for supporti-ng said rod to hold the 'chains in` strip receiving position, a. foot treadle, and means connected With said foot treadle and adapted to engage said rod.

Inv testimony whereof, I affix my signature.
